The performance of photocatalytic degradation is a crucial factor in addressing environmental pollution. This study explores the ability of a composite material consisting of FeFe oxide nanoparticles and single-walled carbon nanotubes (SWCNTs) for enhanced photocatalytic degradation of organic pollutants. The fabrication of this composite material was carried out via a simple chemical method. The produced nanocomposite was analyzed using various techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The catalytic performance of the Fe3O4-SWCNT composite was determined by monitoring the degradation of methylene blue (MB) under UV irradiation.
The results indicate that the FeFe2O3-SWCNT composite exhibits significantly higher photocatalytic activity compared to pure Fe3O4 nanoparticles and SWCNTs alone.
